Changes and New Feature History

PCIe Telemetry

Added support for PCIe Telemetry (NSM Type 2).

Programmable Congestion Control (PCC)

Migrated PCC NP solution from ACE hardware platform to DPA hardware platform. The new capability is applicable to the following 2 modes:

• PCC_INT_EN=True and PCC_INT_NP_RTT_DATA_MODE=INGRESS_BYTE

• PCC_INT_EN=True and PCC_INT_NP_RTT_DATA_MODE=NO_DATA

The first mode is used to support ZTRCC RX bytes in RTT response.

RDMA Telemetry

Added the option to indicate an error CQE event on every selected function per eSwitch manager. This indication is defined as a new WQE including the relevant information about the error (such as: syndrome, function_id, timestamp, QPs num etc.).

The feature is configured using a new general object: RDMA-Telemetry object, and depends on the following new caps: HCA_CAP.rdma_telemetry_notification_types and HCA_CAP.rdma_telemetry.

UID Permissions

Extended kernel lockdown permission set. The following sub-operations can now be called by tools (permission TOOLS_RESORCES) using new HCA capability bitmask field: tool_partial_cap.

The 5 sub-operations are:

• QUERY_HCA_CAP with other function

• QUERY_VUID with direct data

• QUERY_ROCE_ADDRESS with other vport

• SET_HCA_CAP with other function

• POSTPONE_CONNECTED_QP_TIMEOUT with other vport

The new added caps are:

• tool_partial_cap.postpone_conn_qp_timeout_other_vport,

• tool_partial_cap.set_hca_cap_other_func

• tool_partial_cap.query_roce_addr_other_vport

• tool_partial_cap.query_vuid_direct_data

• tool_partial_cap.query_hca_cap_other_func

Cross E-Switch Scheduling

Added support for QoS scheduling across multiple E-Switches grouped in a LAG. VPort members of a Physical Function can be added to a rate group from another Physical Function and rate limits of the group will apply to those VPort members as well.

Jump from NIC_TX to FDB_TX

Added 'table_type_valid' and 'table_type' fields to the steering action (STC) "Jump To Flow" table parameters to enable the user to jump from NIC_TX to FDB_TX and bypass the ACL table.

Jump to TIR or queue from FDB on Tx

Enabled hop reduction by bypassing NIC domain in various use cases. Such action r educes the number of hops (improves PPS) to deal with mass number of flows and devices.

To enable this new capability, a new STC action type "JUMP_TO_FDB_RX" was added to allow jumping into the RX side of a table.

Flex Parser: ARC-IN and ARC-OUT

Increased the maximum number of supported "ARC-IN" from 1 to 8 and "ARC-OUT" from 3 to 8 for the dynamic flex parser.

PSP Crypto Offload

[Alpha] Added support for PSP Crypto offload transport mode.

ZTR_RTTCC Histogram

Added histogram support for rate and Round-Trip Time (RTT) in PCC ZTR_RTTCC.

Bug Fixes

See Bug Fixes in this Firmware Version section.

Memory Slow Release

Added a new command interface "Memory slow release" to enable/disable holding memory pages for a defined period of time. Once the timer expires, the firmware will return the pages to the driver.

PXE Filters

Added support for configuring PXE boot filters' setting from the HII menu to filter only PXE packets (DHCP, TFTP.ARP,ICMP) during boot on UEFI environment.

Precision Timing (PTM)

Added support for Precision Timing (PTM). This new capability ensures seamless operations, synchronized data access, faster response times, and optimal AI performance, enhancing cloud offerings' reliability and scalability.

PTP

Improved the PTP accuracy for ports with link speed of 25G or above.

Kernel Lockdown

Added support for MVTS register via a miscellaneous driver using the access_register PRM command.

AN/LT Visibility

Added an LT logger that provides visibility of the LT status, process and parameters sent and received during the flow.

Steering SF Traffic to a Specific PF MSI-X

MSI-X on SF can be received now through the PF's MSI-X vector.

Bug Fixes

See Bug Fixes in this Firmware Version section.

ODP Event

Added support for the following prefetch fields on ODP event: pre_demand_fault_pages, post_demand_fault_pages.

TRNG FIPS Compliance

Implemented Deterministic Random Bit Generator (DRBG) algorithm on top of firmware TRNG (the source for raw data input) in accordance with NIST SP800-90A.

400GbE, Single-Port, OSFP to OSPF-RHS cable

Added support for 400GbE speed (8X50G) in Single-Port OSFP adapter cards including link training and auto-negotiation when connecting OSFP to OSPF-RHS cables.

PSP

Added support for PSP in Hardware Steering.

NVConfig

Added a new NVConfig option to copy AR bit from the BTH header to the DHCP header.

Steering

Added the option provide field's offset and length in Steering add_action option.

Steering Match

Added support for steering match on packet l4_type through FTG/FTE.

Packet's Flow Label Fields

Added support for setting, adding or copying the flow_label fields from the packet.

BAR Pages

Added support for 64KB pages.

Note: Configuring BAR_PAGE_ALIGNMENT to ALIGN_64KB(2) while one of the following is configured will cause the device to ignore the BAR_PAGE_ALIGNMENT configuration:

• PF_NUM_PF_MSIX>256 on any of the Physical Functions

• VIRTIO_EMULATION_HOTPLUG_TRANS/VIRTIO_NET_EMULATION_PF_PCI_LAYOUT/ VIRTIO_NET_EMULATION_VF_PCI_LAYOUT/ VIRTIO_BLK_EMULATION_PF_PCI_LAYOUT/ VIRTIO_BLK_EMULATION_PF_PCI_LAYOUT=VIRTIO_TRANSITIONAL(1)

Flex Parser Merge Mechanism

Extended Flex Parser merge mechanism to support hardware capabilities.

Flex Parser

Enabled the option to disable the native parser when the parse graph node is configured with the same conditions.

Flex Parser

Added support for father/son headers parsing.

LRO

Added support for tunnel_offload in LRO.

Socket Direct Single netdev Mapped to Two PCIe Devices

Enabled Single Netdev mapping to two PCIe devices (Socket Direct).

Now multiple devices (PFs) of the same port can be combined under a single netdev instance. Traffic is passed through different devices belonging to different NUMA sockets, thus saving cross-NUMA traffic and allowing apps running on the same netdev from different NUMAs to still feel a sense of proximity to the device and achieve improved performance.

The netdev is destroyed once any of the PFs is removed. A proper configuration would utilize the correct close NUMA when working on a certain app/CPU.

Currently, this capability is limited to PFs only, and up to two devices (sockets). To enable the feature, one must configure the same Socket Direct group (non zero) for both PFs through mlxconfig SD_GROUP.

Port Rate Limiting

Added a new access register (PBWS) to set the port maximum bandwidth to a value between 95% to 100%.

ACL

Added support for egress ACL to the uplink by adding a new bit to the Set Flow Table Entry: allow_fdb_uplink_hairpin.

Live Migration

Added support for live migration with MPV and IPSEC. This capability enables creating cross-vhca objects, however, they can only be created between affiliated GVMIs.

If HCA_CAP.migratable bit is set, HCA_CAP.cross_vhca_object_to_object_supported and HCA_CAP.allowed_object_for_other_vhca_access refer to affiliated VHCAs only.

Alternative Bill of Materials (BOM)

NVIDIA is adding an alternative Bill of Materials (BOM) for the specified affected items (MCX713104AS-ADAT & MCX713104AC-ADAT) to enhance production yields. The new alternate BOM requires updating to a minimum firmware version of 28.39.2048.
